@Beta @GwtCompatible @Immutable public final class MediaType extends Object
*
character is treated as a wildcard and is used to represent any acceptable
type or subtype value. A media type may not have wildcard type with a declared subtype. The
*
character has no special meaning as part of a parameter. All values for type, subtype,
parameter attributes or parameter values must be valid according to RFCs 2045 and 2046.
All portions of the media type that are case-insensitive (type, subtype, parameter attributes)
are normalized to lowercase. The value of the charset
parameter is normalized to
lowercase, but all others are left as-is.
Note that this specifically does not represent the value of the MIME Content-Type
header and as such has no support for header-specific considerations such as line
folding and comments.
For media types that take a charset the predefined constants default to UTF-8 and have a
"_UTF_8" suffix. To get a version without a character set, use withoutParameters()
.

java.lang.Object
The equals
method implements an equivalence relation
on non-null object references:
x
, x.equals(x)
should return
true
.
x
and y
, x.equals(y)
should return true
if and only if
y.equals(x)
returns true
.
x
, y
, and z
, if
x.equals(y)
returns true
and
y.equals(z)
returns true
, then
x.equals(z)
should return true
.
x
and y
, multiple invocations of
x.equals(y)
consistently return true
or consistently return false
, provided no
information used in equals
comparisons on the
objects is modified.
x
,
x.equals(null)
should return false
.
The equals
method for class Object
implements
the most discriminating possible equivalence relation on objects;
that is, for any non-null reference values x
and
y
, this method returns true
if and only
if x
and y
refer to the same object
(x == y
has the value true
).
Note that it is generally necessary to override the hashCode
method whenever this method is overridden, so as to maintain the
general contract for the hashCode
method, which states
that equal objects must have equal hash codes.

The general contract of hashCode

application to another execution of the same application.

method, then calling the hashCode
method on each of
the two objects must produce the same integer result.
Object.equals(java.lang.Object)
method, then calling the hashCode
method on each of the
two objects must produce distinct integer results. However, the
programmer should be aware that producing distinct integer results
for unequal objects may improve the performance of hash tables.
As much as is reasonably practical, the hashCode method defined by
class Object
does return distinct integers for distinct
objects. (This is typically implemented by converting the internal
address of the object into an integer, but this implementation
technique is not required by the
Java™ programming language.)
